Bacterial infections on the scalp often present a combination of symptoms, with redness and swelling being key indicators. When bacteria invade the skin, they can cause inflammation, resulting in red, swollen areas. This reaction is a direct response by the body's immune system trying to fight off the infection.

While pustules and other signs such as dry skin or excessive oiliness can be associated with various scalp conditions, redness and swelling are more specific indicators of an inflammatory response to a bacterial infection. The presence of these symptoms can suggest that underlying irritation or infection is occurring, thus guiding a barber or stylist in understanding the condition of the scalp and the best course of action for treatment or referral to a healthcare professional.
